Window zones and climate zones across Maine
Maine has no split on the federal window map. The ENERGY STAR climate zone map (August 2025) shades the entire state as Northern, so a window qualified for that zone meets the ENERGY STAR criteria in every Maine county, from York to Aroostook.
The energy code map is not quite as simple. In the county tables of PNNL-33270, prepared for DOE (2021 data), 15 of Maine's 16 counties are IECC zone 6A, where the A stands for moist, and one county is zone 7, which carries no moisture letter. The residential code sets window requirements zone by zone, so a crew working in both zones checks which table applies.
Which energy code Maine window jobs follow
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
Maine moved to a newer residential code in 2025. The DOE Building Energy Codes Program page for Maine (checked October 7, 2026) lists the 2021 IECC with amendments as the current residential code, with an adoption date of January 7, 2025 and an effective date of April 7, 2025. The same page shows that the state made amendments and that REScheck can be used to show compliance.
For a window buyer the date matters because a replacement installed today is held to the 2021 edition, not the one before it. Contractors who quote full-frame work on older Maine houses build that edition into the price and the product list.
How old and how valuable Maine homes are
A little more than half of Maine's homes predate 1980. The Census Bureau's table B25034 (ACS 5-year 2020-2024) puts that share at 54.4%, and table B25035 for the same years gives 1977 as the median year a Maine housing unit was built.
The 1970s layer is large too. The same table B25034 (ACS 5-year 2020-2024) counts 99,203 Maine units built from 1970 to 1979, and many of those houses are now on their first or second set of windows. A request form that asks for the approximate year the house was built helps a crew decide whether to bring insert units or plan for full-frame work and trim repair.
The median value of an owner-occupied home in Maine is $296,600 in table B25077 (ACS 5-year 2020-2024). Window crews that sell premium frames or full-house packages often set a home value range alongside the ZIP code list.
Maine contract rules that name window work
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
The Attorney General's home construction contracts page says the state does not license home contractors; Maine regulates the contracts instead. The definition section of the home construction contracts chapter, 10 M.R.S. 1486 (checked October 7, 2026), says a home construction contract covers building, remodeling or repairing a residence, and it lists window replacements by name next to carpeting and electrical, plumbing and heating work.
The next section, 10 M.R.S. 1487 (Maine Revised Statutes, checked October 7, 2026), applies to any such contract for more than $3,000 in materials or labor. That contract must be written and signed by both sides before work starts, must state estimated start and completion dates, and must limit the initial down payment to no more than 1/3 of the total price. It also has to include a warranty statement and a change order statement in the wording the statute sets out.
The Attorney General's position on contractor licensing and Maine's door-to-door cancellation rule are covered on leads in Maine.
Filters Maine window buyers set
Each field below ties back to a Maine fact on this page.
- ZIP code: one window zone covers the state, so territory is set by where crews drive, not by product line.
- Number of windows and scope: the job size decides whether the written contract statute applies and how large the down payment can be.
- Home age: pre-1980 houses often need full-frame work that the current energy code edition governs.
- Homeowner status: the owner or lessee is the party who signs the contract under Maine law.
Where buyers filter in Maine

- Bangor: 157,967 (July 1, 2025 estimate)
- Lewiston-Auburn: 116,487 (July 1, 2025 estimate)
